SHOE-JACK.

SPECIFICATION forming part of Letters Patent No. 386,867, dated July 31,1888.

Application filed May 1, 1888. Serial No. 272,400.

To all whom, it may concern:

Be it known that 1, WILLIAM G. DAVIS, of Lynn, in the county of Essexand State of Massachusetts, have invented new and useful Improvements inShoe-Jacks, of which the following is a specification.

In the accompanying drawings, in which similarletters of referenceindicate like parts, Figure l is an elevation of a shoejack embodying myinvention, with the last in position thereupon, certain portions of theholder being represented as broken out, the better to illustrate theinvention. Fig. 2 is a vertical section on line 00, Fig. 1.

A represents the base, which in practice is adapted to be screwed to thebench.

B is a round metallic box, whose bottom B is secured to the base A bymeans of the bolt 0, as shown, whereby said box is enabled to be rotatedon the stationary base. A rubber gasket, D, lies on the bottom B andsurrounds the bolt G, and a plate, d, centrally perforated to receivethe bolt, lies upon the gasket. By means of the nut d and checknut d thepressure of the plate upon the gasket may be regulated, thus providingsuitable friction, so that the box B may not be too easily rotated.

E is. a plate or cover provided with the hinge E, whereby it ispivotally secured by means of the pin 0 to the box B, said box beingprovided with the ears B, through which said pin extends. These ears areprovided with steps b, which limit the motion of the plate E, as,whensaid plateis tipped orswung over to its greatest extent, the wings E,extending from the hinge E, strike and rest upon said steps b. In orderto provide friction whereby the plate may be held in any a e desiredposition, a washer of soft metal, 0, is placed between the hinge E andone of the ears B, as shown.

H represents the holder, of substantially the shape shown, pivotallysecured by means 5 of the bolt I to the plate E. A gasket, J, disk K,and nuts K and K are provided similar in construction and purpose to thegasket D, disk d, and nuts (6 and d. The

gasket J is held in position by means of the (No model.)

annular flange E, extending downward from the plate E. The holder H isprovided with a toe-piece, H, which has grooves it formed in it in theordinary manner for the adjustment and reception of the toe-support L,which is in this invention made so as to bend or curve outward towardthe toe of thelast S, while the grooves which receive itslower end aresubstantially vertical. The heel-support I, which holds the heel of thelast in the ordinary manner, is pivoted at a to the vertical 6o arms 0,extending from the holder. A stiff spring. P, lies between the lower armof the lever N and a partition, H, in the holder, whereby the toe of thelast is held firmly down upon the toe support L,

It will thus be seen that the jack may be adjusted to suit the operator,first, by rotating the box B upon the base A, by which it may be adaptedfor a right or left handed workman; second, by tipping the plate E, asshown in broken lines in Fig. 2; and, third, by rotating the holder H,whether said plate be in its normal position or tipped.

All the parts of this device are preferably constructed of metal. 7

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The herein-described improved shoe-jack, consisting, essentially, ofthe following parts, viz: the stationary base A, box B, adapted to berotated upon said base, plate E, pivotally secured to said box, wherebyit may be swung up, as shown, and last-holder II, adapted to be rotatedupon said plate, substantially as and for the purpose set forth.

2. The combination of the base A, the bolt 0, gasket I), disk (I andnuts, the box B, provided with the ears B, the bolt I, gasket J, disk Kand nuts, the plate E, provided with 0 the hinge E and flange E, and theholder H, provided with the heel support N and toesupport L,substantially as and for the purpose described.

WILLIAM O. DAVIS.
